    翻译是一种语言文字的实践,是用一种语言文字把另一种语言文字所表达的思想准确而完整地重新表达出来的语言实践活动,是语言艺术的再创造。英汉两种语言在结构和搭配上存在很大差异,有各自不同的特点,掌握一定的翻译技巧对译文的质量起着至关重要的作用。翻译技巧不同会使译文风格千差万别,翻译技巧是否得当直接影响译文的质量。美国著名作家雨果•德•加利丝教授被称为“人工智能之父”,他善于创造新词;长短句相间,富于文采;前后照应,结构紧凑。他的作品具有研究翻译技巧的价值。 本文旨在通过翻译雨果•德•加利丝的代表作《多元人与单元人》分析总结翻译过程中所使用的多种英译汉...Translation is the linguistic practice, which is to make a faithful representation in one language of what is written or said in another language. In other words, it is an art of re-creation in terms of language. There are great differences between English and Chinese in structures, collocations and characteristics.

    Preparation and Characterization of the HA/MWNTs and HA/TiO2 Nanotubes Composite Biomaterials

    羟基磷灰石(HA)是人体骨骼和牙齿的最主要无机成分,人工合成的HA具有良好的生物相容性和生物活性,但HA脆性大、强度低,抗折强度和断裂韧性指标均低于人工致密骨的特性,限制了它在临床的实际应用。医用金属钛表面涂覆HA可结合金属材料的良好力学性能和HA良好生物性能,已被广泛地用作人体硬组织替代材料。然而,HA与钛基底热膨胀系数失配造成的残余应力,降低了涂层与基底之间的结合力,临床应用中常出现涂层脱落或植入体松动现象。二氧化钛纳米管具有良好的生物活性、抗腐蚀性及耐磨损性,因此,发展HA/二氧化钛纳米管复合增强体,可望起到增韧补强作用,提高HA涂层的力学性能,具有重要的临床应用价值。磷酸钙骨水泥(CP...Hydroxyapatite (Ca10(PO4)6(OH)2, HA) is the main inorganic component in natural bone and tooth.

    液固两相射流冲击磨损的数值计算与实验研究

    应用实验与数值模拟研究液固两相射流对不锈钢材料的冲蚀磨损行为,分析不同质量分数、粒径情况下样品的平均磨损率,并基于数值模拟预测不同射流速度工况下的冲刷磨损率,最终建立冲刷磨损率与射流速度的关系模型。研究结果表明:单相射流流场的数值模拟结果与实验结果吻合较好;在距离射流中心区域不同径向距离上,平均速度的变化趋势较一致;在近壁面处,射流轴向速度突然减小,造成雷诺切应力增大。在远离壁面处,其法向速度逐渐增大,脉动速度相应增大,雷诺切应力增大;当射流继续远离壁面时,雷诺切应力开始减小直到趋近于0;在喷嘴正下方,压力分布存在1个滞止区,此处压力高于四周压力;下游冲刷磨损率先升高再稍微下降,而上游冲刷磨损率明显下降;实验样品表面微观测试结果验证了不同区域冲刷磨损率分布的正确性。国家自然科学基金资助项目(51776225,51376153,51406235);;中国石油大学(北京)科学基金资助项目(C201602)~

    Revista Migrações

    Com este número da Revista Migrações retrata-se de forma aprofundada o papel do movimento associativo imigrante na construção de uma sociedade intercultural onde se aliam os dois objectivos definidos, à primeira vista, como opostos de preservação da identidade cultural de origem e integração na sociedade de acolhimento. A experiência acumulada pelo ACIDI neste domínio comprova a justeza do princípio trabalhar para os imigrantes, com os imigrantes. Esta co-responsabilidade na construção das sociedades democráticas onde todos somos participantes leva-nos a desejar um associativismo imigrante cada vez mais forte, contribuindo para quebrar a solidão daqueles que procuram, longe das suas comunidades de origem, um futuro melhor para si, em troca do trabalho que prestam para o desenvolvimento da comunidade que os acolhe.peerrewie

    3 to 5 Years Old Children’s Behavioral and Verbal Performances in Level 1 Perspective-Taking

    为考察3~5岁儿童一级观点采择的行为表现与言语报告之间的潜在差异,本研究采用&quot;单面镜&quot;范式设计了两个实验。实验1中,54名儿童成对与实验者一起完成观点采择游戏,逻辑回归分析结果表明3-5岁儿童的行为表现不存在显著差异(B=?0.225,Wald=0.38,p=0.541)。方差分析也没有发现儿童的行为表现和言语报告存在差异。由于实验1中的编码系统存在一些局限,并且缺少对儿童偏好的控制,因此在实验2中进行了改进。实验2选择了另外60名3~5岁儿童完成藏玩具游戏。方差分析发现了实验范式类型(行为表现或言语报告)、年龄和性别的三因素交互作用(F(2,48)=3.55,p=0.037,&eta;2=0.13)。结果表明随着年龄增加,男孩与女孩一级观点采择的行为表现都显著提高,而男孩言语报告的提高程度显著低于女孩。总体而言,考察儿童一级观点采择时,行为表现可能比言语报告提供更多信息。</p
